Specification of Letters Patent.

Patented May 26, 1908.

To all whom it may concern:

Be it known that we, LEWIS W. HARRING- ToN, a citizen of the United States, and a resident of Short Hills, county of Essex, and

.State of New Jersey, aIIdBERNARD LEON- ARD, a citizen of the United States, and a resident of the city and county and State of New York, have invented a new and useful Improvement in Apparatus for Drawing Liquids, of which the following is a specificatlon.

Our invention relates to apparatus for drawing liquids.

It is especially adapted for use in cases where liquids are drawn oif at a point distant from the vessel containing the supply of said liquid. Its object is to provide means for keeping such liquids'coo on their passage from the supply vessel to the point where the liquid is drawn off for consumption; also to provide a new and improved supplementary chamber at the drawing off polnt, that can also serve as a drain board without permitting the waste to enter the chamber, and yet be easily accessible from "the top.

It consists of the novel device and combinations hereinshown and described.

Our invention may be used with any kind of liquid, but it is es ecially useful in connection with a charged iquid such as beer or ale. It is often the practice in drawing such liquids to locate the su ply vessel or vessels in a refrigerator, placed fer example, in the cellar, and to draw off the liquid through s igots located at some distance therefrom, or example, located on the counter of a saloon, pipes running from'the supply vessels in the refri erator to the spigots on the, counter. Whi e the beer, for example, is kept cool in the supply vessels in the refri erator, it is apt to become warmed to an o 'ectiona'ble degree on its passage through t e pipes. In many cases such li uid is spoiled on such passage and in mosta 1 cases it is more or less injured. By means of our improved device we are enabled to effectually prevent any such warming of the beer or other li uids, and we are enabled to keep it cool until it is discharged from the spigot. We are also enabled to regulate the degree of temperature of the beer or other liquids by means of our improved device so that some can be served very cold and others not quite so cool.

Our improved device afiords more econbeers or liquids omy in many directions, for instance, the

sasu'ng of ice bills, the saving of plumbing and the savin of labor. Heretofore it has been the practice to have an ice tank just back of the drawing ofl spigots having a long coil of pipe in which the iquidis carried in said tank so that cracked ice may be packed in and around the pipe to cool the liquid. This is all done away with in our improved device and is unnecessary.

While our im rovement may be used with any li uid, we ave shown in the drawings and M1 now proceed to describe the apparatus containing our improvement in its ferred form and shown as adapted for the drawing of beer.

Referrin to such drawing Figure 1 represents an e evation of the preferred form of our improvement as thus applied, parts being shown in section, for the purpose of clearness; Fig. 2 represents a vertical, longitudinal section through our improved supplementary chamber.

Referring to the specific form of our invention shown in the drawin s 1 represents a refrigerator of any suitab e construction located, for exam 'le, in the basement, 2 being the icebox o the usual construction; 3, 3 represents vessels for holding the supply of liquid here shown as beer barrels. ber of these vessels contained in the refrigerator may of course, be varied from one up-' ward as desired.

4 represents a series of spigots at the drawing ofl point, two of these spi ots are connected with the two vessels 3, 3, y ipes 5, 5. 6, 6 are conduits leading from t e refrigerator to the drawing off point. They are arranged to receive the pipes 5, 5 which run from the vessels to the spigots. These conduits are preferably covered with a non-conducting covering 7. Conduits 6, 6 are made of sufiicient size to easil hold one of the pipes 5, 5 and preferab y are made large enough, so that a suflicient air space will exist in and around the pipes 5, 5 in the conduits. At the point where the pipes from the vessels 3, 3 enter the'conduits we seal the conduit so that no air can enter at that point from the refrigerator. To permit air to enter the conduits from the refrigerator we rovide separate conduits 24, 24 for each of t e main conduits 5, 5. In each of these supplementary conduits 24 we place a valve 25 so as to control the amount of cold air which enters pre- , 20 frigerator.

I the conduits 5, 5. The Opening and closing or the partial opening or partial closing of this valve may be controlled in any manner desired. In the drawing we have shown a long rod 26 running up to a oint near where the s igots are situated whic rod has a small whee 27 situated on top of it for the bartender or erson in charge to open or close the valve as esired. By means of these supple- 1O ,mentary conduits havin valves therein, cold air can be closed off entlrely from any of the conduits or can be let in in a small or large quantity as desired.

In order to insure a circulation of cold air through the conduits from the refrigerator,

5 tails of these form no part of the invention and are not shown. e prefer to arrange the fan in an elbow, such as shown at 11 in Fig. 1. By means of the fan 9 the air can be circulated very rapidly through the refrig- 0 erator 1, the condults 6, 6, the supplementary chamber 13, pi e 8 back to the refrigerator, or can be circu ated slowly by reducing the s ed of the fan or stopping it altogether and a owing the cool air to circulate of itsown accord. There is ample room for the cold air to pass between the lades of the fan when the fan is stationary. The sgigotsA may be connected directlyto the con ults but we prefer in practice to m- 40 terpose a supplementary chamber or refrigerator 13 atornear the drawing ofi" oint. Such chamber may,if desired,be packe with ice but this is not necessary in our improved device. In Fig. 2 of thedrawings we have shown this supplementary chamber or refrigerator contalning the pipes 5, 5 through WlllCh the liquid is conveyed to the spigots.

14 is a perforated dram plate of the usual construction, which as shown is arranged over or on top of the supplementary chamber.

15 is an im erforate cap, preferably removable, adapte to form a coverfor the interior of'the chamber'underneath the drain plate.

It may be fitted in any suitable manner, but

we prefer to provide it with a depending flange 16, surrounding the cap and dippin down intothe surrounding trou h 17, formed by the L-shaped walls of the c amber 13 'as 00 shown inFig.'2, and adapted to hold a liquid.

By these means a water seal is provided, preventing the escape of air from the interior of chamber 13. As the cap 15 is preferably removable, it can easily be taken off for cleansing purposes or in order topack the chamber with fee if desired or for any other purpose. As waste beer drips through the drain plate, it falls upon the imperforate cap 15, and flows off into trough 17.

1 8 is a discharge outlet from the trough, carrying off the waste beer. It connects with a discharge ipe 19 as shown in Fig. 1. By these means t e liquid in the trough will never rise too high.

20 is a discharge pipe at the bottom of the chamber 13, for the esca e of water, and it is shown as connecting wit pipe 19.

I While the refrigerator is shown in the drawing as located in the basement, and the spigots as located upon the floor above 2-1, on counter 22, we do not limit ourselves to such an arrangement. The refrigerator may be placed in any suitable location, either below, on thefsame level with, or above the spigots. Many changes in and modifications of the particular form of device shown in the draw- .mgs may be made without departing from our invention, the essentials of which are set forth in the claims appended hereto.

B means of our improvement, the liquid can e drawn off at any desired point, without being warmed in its passagefrom the sup ly vessel, and the taste and quality of iquid are preserved. By means of our supplementary chamber, the waste is employed to forma water seal for the chamber, all ex- 'cess of waste is removed, and access can be easviy1 had to the chamber itself. l y at we claim as new and desire to secure by Letters Patent is as follows:
